Right ventricular systolic function and mechanical dyssynchrony in ischemic or non-ischemic dilated cardiomyopathy: A speckle-tracking study.

Aim: This study assessed RV dyssynchrony (irrespective to QRS duration) and RV systolic function in non-ischemic dilated cardiomyopathy (NIDCM) versus ischemic dilated cardiomyopathy (IDCM) patients by using different echo-Doppler modalities.

Methods: Eighty-five cases (48 patients with DCM [whether ischemic or non-ischemic] and 37 age-matched healthy controls) were studied. Conventional echo-Doppler study, tissue Doppler (TDI), and speckle tracking (STE) were carried out to measure LV and RV systolic function.

Functional outcomes in post Covid-19 patients with persistent dyspnea: multidisciplinary approach.

Background: Post-acute sequelae of SARS-CoV-2 (PASC) have emerged as a major health issue in patients who have previously been infected with Covid-19 virus.

Purpose: we aimed at the assessment of functional outcomes in post Covid-19 patients with persistent dyspnea using a multidisciplinary approach including clinical assessment, laboratory investigations, exercise ECG, and different echo-Doppler modalities, including left atrial functions.

Methods: The current observational randomized controlled study conducted on 60- patients one month after recovery from Covid-19 infection presented with persistent dyspnea compared to 30 healthy volunteers.
